... Houston and the University of California, Irvine, describe the versatile light-sensing protein at levels of resolution smaller than a nanometer--one billionth of a meter. "High-resolution X-ray crystallography revealed the light-absorbing part of the protein was present in two alternative positions, sugges...

.... 24 issue of the journal Science, the researchers describe how a gene called phytochrome-interacting factor 1, or PIF1, affects the production of protochlorophyll, a precursor of the chlorophyll used by plants to convert the sun's energy into food during photosynthesis. While a seed germinates under soil,...

...shed in Science on September 24, 2004, the authors describe how the neck may have been used to capture prey. "This is important research because we have finally explained the functional purpose of this strange, long neck," said Olivier Rieppel, PhD, a co-author of the Science paper and chair of geology and ...

... colleagues Chris Todd Hittinger and Antonis Rokas describe the discovery of a set of seven genes caught in the act of fossilization. In the Japanese yeast, known to scientists as Saccharomyces kudriavzevii, the Wisconsin scientists found the decaying genes that, when intact, are all functionally related and...

...er, he is looking for a set of universal laws that describe the rhythms of plant and animal life. The principles that he and his colleagues are discovering appear to reveal deep biological truths about everything from the way cells consume nutrients to the growth rates of trees to how deforestation could affe...

... the September 16 issue of Nature, the researchers describe cells that produce a glucagon-like hormone, which are akin to alpha cells in mammals. These two cell types within the pancreatic islets are the main cellular sensors of blood-sugar levels. Together the fly's insulin- and glucagon-producing cells coul...

...udy, along with advances that are expected soon to describe the entire Populus genome DNA sequence, will help scientists find specific genes in a matter of minutes using computational approaches. Such discoveries would have taken decades or centuries prior to these databases, Strauss said. "Once you know a l...
